摘要：Ample research has been devoted to mobile computing and database query management with the beginning of porta ble computers and wireless communication systems. Query processing is crucial in distributed environment rather than in centralized environment because a large number of parameters affect the performance of distributed queries, relations may be fragmented and/or replicated and considering many sites to access, query response time may become very high. It is quite obvious that the performance of query management is critically depending upon the ability of the framework to derive efficient query processing st rategies. Query management challenges to reduce the quality of data transferred. The query management has several problems relate to larger set of queries, bandwidth limitation, query processing time, query access time and query response time. The goal of query management is to execute such queries as efficiently as possible in order to minimize response time. This paper explorer the frameworks with its technical analysis which focuses performance of query processing based on various parameters such query e xecution time, query response time, query optimization, database size, location tracking and location management in centralized and distributed manner with communication cost in mobile environment
